Reverse Proxy a Solr Instance

It’s encouraged that you secure your Solr instance by placing the application on a different file server and behind a firewall. That’s an issue if you are trying to consume data from the Solr instance leveraging AJAX techniques.

Problems:

www.website.com and Apache Solr live on separate boxes.

A firewall protecting Apache Solr plus the cross-domain issue does not expose the necessary end-point to consume via AJAX.

Depending on your sys admin setups, Solr may not live on a fully qualified domain (ie. http://12.34.56.789:8983/solr/#/)

An AJAX call to consume the Solr instance’s JSON/XML won’t work cross-domain.
